Abstract: An outer needle cover for a pen needle assembly is provided with a breakaway flange. Prior to use, the flange is connected to a body of the outer cover. The flange has a reduced cross sectional thickness portion that facilitates separation of the flange from the outer cover, thereby reducing the outer diameter of the outer cover. The reduced outer diameter of the outer cover allows the outer cover to be received by a pen cap of an existing injector device.

Abstract: A pump (10) includes a housing, a stator (20) supported in the housing, and a rotor assembly (30). The rotor assembly (30) includes a rotor (32) supported in the housing for rotation relative to the stator (20) about an axis (12). The rotor assembly (30) also includes a first impeller (34) operatively coupled to a first axial end of the rotor (32) for rotation with the rotor about the axis (12). The rotor assembly further includes a second impeller (36) operatively coupled to a second axial end of the rotor (32), opposite the first axial end, for rotation with the rotor about the axis (12). The rotor assembly (30) is movable along the axis (12) relative to the housing to adjust hydraulic performance characteristics of the pump (10).

Abstract: In a centrifugal flow blood pump, usable in left ventricular assist applications, blood is pumped from an inlet (16) to an outlet (22) by a primary impeller (18). A portion of the blood that enters the pump follows a secondary channel (24) where a secondary impeller (70) routes the blood to lubricate a bearing between an impeller assembly (14) and a post formed by a component of the pump housing. The unique shape of the secondary impeller (70) prevents blood stagnation and provides for a well-washed fluid bearing.

Abstract: A hot wire igniter for igniting a gaseous or atomized fuel is disclosed. The coil of the hot wire igniter is formed from a thin high temperature, iron, chromium, aluminum alloy having a center section that is tightly wound. The coil turns initially do not touch one another and each end of the coil is attached to a rod that is received within an insulator member. The rods are connected to a power source. The coil portion of the hot wire igniter is received within a gas collector box which is attached to the burner to be ignited. Application of the power source to the lead-in rods causes the coil of wire to reach a temperature in excess of the ignition temperature of the fuel mixture which surrounds same causing the ignition of the mixture.

Abstract: A hot wire igniter for igniting a gas appliance is disclosed. The coil of the hot wire igniter is formed from a thin high temperature, iron, chromium, aluminum alloy having a center section that is tightly wound. Alternatively, the coil can be formed from an alloy of platinum and iridium, or a similar high temperature metal alloy. The coil turns initially do not touch one another and each end of the coil is welded to a lead-in rod that is received within an insulator member. The lead-in rods are connected to a power source. The coil portion of the hot wire igniter is received within a gas collector box which is attached to the burner to be ignited. Application of the voltage source to the lead-in rods causes the coil of wire to reach a temperature in excess of the ignition temperature of the gas-air mixture which surrounds same causing the ignition of the mixture.

Abstract: A method of determining or assessing remaining life in insulation material includes using a computerized analytical model and supporting equipment to assess margin between an electrical insulation sample's given (i.e., known) void parameters (such as size and density) and void parameters corresponding to the threshold to integrity failure. The margin is then correlated to remaining life through use of known void growth rates, which are a function of temperature and other environmental service factors.

Abstract: A method of detecting and measuring voids in insulation material includes: providing a sample of insulation material; providing an imaging system for generating an image of the sample of the insulation material; analyzing the image to detect the presence of voids therein; and measuring the voids present in the sample to determine their size and density. Preferably, a nondestructive imaging system is utilized to detect and measure the voids.
